Adding several subtitles to a movie is very easy with HandBrake.
By doing so, you will be able to switch between subtitles during the video playback.
After you add the subtitles, you just need to fire up the video in your favorite video player.
Most video players show subtitle automatically.
If your video player doesnt show any subtitle, perhaps the subtitle needs to be activated manually.
